Question

我使用capistrano 4.4，nginx，unicorn。当我部署时，我有这样的错误：

bin / cap production deploy：check工作正常。

当我第一次运行bin / cap生产部署时，我有一个错误：

...
 [7e794b92]     Cloning into bare repository   
'opt/www/foreignernetwork/repo'...
INFO [7e794b92] Finished in 3.847 seconds with exit status 0 (successful).
DEBUG [19e30ae6] Running /usr/bin/env if test ! -d opt/www/foreignernetwork/repo; then echo "Directory does not exist 'opt/www/foreignernetwork/repo'" 1>&2; false; fi as deployuser@128.199.226.61

DEBUG [19e30ae6]    Directory does not exist 'opt/www/foreignernetwork/repo'
(Backtrace restricted to imported tasks)
cap aborted!
....

当我再次运行它时，它说：

[4daafe62] Command: cd opt/www/foreignernetwork && ( GIT_ASKPASS=/bin/echo GIT_SSH=/tmp/foreignernetwork/git-ssh.sh /usr/bin/env git clone --mirror https://github.com/KonstantinSmirnov/foreignernetwork.git opt/www/foreignernetwork/repo )
DEBUG [4daafe62]    fatal: destination path 'opt/www/foreignernetwork/repo' already exists and is not an empty directory.
(Backtrace restricted to imported tasks)
cap aborted!
....
SSHKit::Command::Failed: git exit status: 128
git stdout: Nothing written
git stderr: fatal: destination path 'opt/www/foreignernetwork/repo' already exists and is not an empty directory.
....

如果我删除此文件夹，它会再次重复。

以下是我的文件：

deploy.rb：

lock '3.4.0'

set :application, 'foreignernetwork'
set :repo_url, 'https://github.com/KonstantinSmirnov/foreignernetwork.git'
set :scm, 'git'
set :deploy_via, :copy

set :deploy_to, 'opt/www/foreignernetwork'
set :user, 'deployuser'
set :linked_dirs, %w{log tmp/pids tmp/cache tmp/sockets}
set :ssh_options, { :forward_agent => true, :port => 12531 }
set :use_sudo, true

namespace :deploy do

%w[start stop restart].each do |command|
desc 'Manage Unicorn'
task command do
  on roles(:app), in: :sequence, wait: 1 do
    execute "/etc/init.d/unicorn_#{fetch(:application)} #{command}"
  end
end
end

  after :publishing, :restart

  after :restart, :clear_cache do
on roles(:web), in: :groups, limit: 3, wait: 10 do
  # Here we can anything such as:
  # within release_path do
  #  execute :rake, 'cache:clear'
  # end
    end
  end

end

production.rb：

role :app, %w{deployuser@128.199.226.61}
role :web, %w{deployuser@128.199.226.61}
role :db, %w{deployuser@128.199.226.61}

unicorn.rb：

root = "/opt/www/foreignernetwork/current"
working_directory root
pid "#{root}/tmp/pids/unicorn.pid"
stderr_path "#{root}/log/unicorn.log"
stdout_path "#{root}/log/unicorn.log"

listen "/tmp/unicorn.foreignernetwork.sock"
worker_processes 1
timeout 30

你可以帮我弄清楚如何解决它吗？已经挖掘出一切......

您可以尝试替换

role :app, %w{deployuser@128.199.226.61}
role :web, %w{deployuser@128.199.226.61}
role :db, %w{deployuser@128.199.226.61}

与

server '128.199.226.61', roles: %w(app web db), primary: true, user: 'deployuser'

在你的production.rb

中

据我所知，当您编写三个与一个IP相关的单独条款时，capistrano遇到竞争条件，试图在不同角色下执行相同的任务。
